Garden Reach Water Works has the capacity to produce 120 MGD of potable surface water. There exist some pockets where the inhabitants are not getting sufficient quantity and this condition may aggravate further due to increase of population.
Considering these issues, it has been proposed to augment the present capacity of Garden Reach Water works by another 15 MGD Plant. The plant is designed to consists of rapid sand filtration system with a pre-treatment of flocculator and plate settler type of clarifier.
An underground reservoir of 2.5 MG capacity along with a pumping station is also a part of this project. Raw water for this project is provided by the Raw Water Pumping Station of GRWW Phase II.
At the beginning this water treatment plant will supply potable water into the Behala Booster Pumping Station, wherefrom water will be served at its command area including the said municipalities.
The proposed Akra reservoir will also be benefited by this project. In future, in the adjacent localities like Joka, Thakurpukur, Chota Kalikapur etc., where at present surface water is not reaching the inhabitants, will be provided by potable surface water from this water treatment plant also.
In the year of 2024, about 34 lakhs people will be benefited with adequate potable surface water within its command area.
The project report was prepared by KMWSA, and with the approval of KMDA, Kolkata Municipal Corporation is providing the fund of the entire project.
The implementation period of this project of constructing the plant proper is planned for 18 months. On completion, the assets created will be handed over to Kolkata Municipal Corporation for Operation and Maintenance, pumping station and booster chlorinator.
To feed the water from GRWW into this UGR, a dedicated pipeline will be shortly laid by KMC.
